Progress towards understanding the structure, function, and ecological significance of small stream channels and their riparian zones

چکیده
Incomplete knowledge of the ecological functions of small streams and their riparian zones, particularly their roles in larger watershed and landscape contexts, contributes to confusion and debate about the levels of riparian vegetation retention required along small streams for the purpose of protecting aquatic ecosystems, riparian wildlife, and water quality. As a consequence, there are marked differences in riparian forestry practices and management among jurisdictions throughout North America. To aid in resolving these issues, a symposium on small streams and their riparian zones was held at The University of British Columbia from 19 to 21 February 2002, which brought together scientists, managers, and practitioners and provided a forum for the presentation and discussion of emerging research results. This special issue includes a selection of papers presented at that symposium as well as one solicited paper. Résumé : Une connaissance insuffisante des fonctions écologiques des petits cours d'eau et de leurs zones riveraines, particulièrement à l'échelle plus vaste du bassin versant et du paysage, alimente la confusion et les discussions concernant le degré de rétention de la végétation qui est nécessaire le long des petits cours d'eau, pour la protection des écosystèmes aquatiques, de la faune riveraine et de la qualité de l'eau. Il y a par conséquent des différences marquées dans l'aménagement et les pratiques forestières en zone riveraine entre les différentes juridictions partout en Amérique du Nord. Dans le but de contribuer à résoudre ce problème, un symposium traitant des petits cours d'eau et leurs zones riveraines a été organisé à The University of British Columbia du 19 au 21 février 2002. Ce symposium a rassemblé des chercheurs, des gestionnaires et des praticiens et a permis de présenter et de discuter les résultats des travaux de recherches les plus récents. Cette section spéciale inclut un choix d'articles présentés lors de ce symposium ainsi qu’un

USDA Forest Service Gen. Tech. Rep. PSW-110. 1989. 3 Riparian zones occur at interfaces — ecological interfaces between different ecosystems and conceptual interfaces between different scientific disciplines. The plethora of definitions and delineations of riparian zones are inconsistent, confusing, and often contradictory, reflecting the diversity of disciplines, perspectives, and objectives f...

Effective river ecosystem management requires that the existing hydrologic regime be characterized in terms of the natural hydrologic regime and the degree to which the human-altered regime differs from natural conditions. This is known as Range of Variation Approach (RVA) and can be used for variation of stream flow, range of variation and appraisal of dam impacts on riparian zones. In this pa...
متن کاملSession I. Assessment and Rehabilitation of Hydromorphological Processes in Rivers
Streams and their riparian zones provide typical examples of naturally speciesrich, dynamic habitats. Under natural conditions, spatial and temporal variation in flooding disturbance coincide with a strong hydrological gradient from the channel to the uplands, generating a heterogeneous environment with corresponding high plant and animal diversity. Yet, streams and their riparian zones are hig...
متن کاملWhat are the effects of wooded riparian zones on stream temperature?
Background: Predicted increases in stream temperature due to climate change will have a number of direct and indirect impacts on stream biota. A potential intervention for mitigating stream temperature rise is the use of wooded riparian zones to increase shade and reduce direct warming through solar radiation. To assess the effectiveness of this intervention, we conducted a systematic review of...
متن کاملProcess - Based Stream - Riparian Modeling System to Assess Stream
This paper describes a comprehensive stream-riparian modeling system to evaluate the effects of channel-riparian zones on stream Total Maximum Daily Loads (TMDLs). Nonpoint source pollutants emanating from agricultural fields are major contributors to the ecological impairment of stream channels. Nutrients and sediments are the principle sources of surface water impairment. The edge-of-field sy...
